Problems solved by technology

The two-stage coaxial multi-ribbed pulley of this split structure has disadvantages such as poor fastness, large runout, difficulty in ensuring the coaxiality between the two stages, unsightly overall appearance (there is a welded seam on the surface), and the surface treatment is easy to corrode internal materials, etc.
Moreover, the existing spinning machines are two- and three-station spinning machines, with few processing stations, and the processing of the secondary coaxial poly-wedge belt pulley requires multiple replacements of the spinning wheels and multiple adjustments of the horizontal spinning height, which cannot be done at one time. It is difficult to guarantee the coaxiality between the two stages due to the clamping process, so it is not suitable for the processing of the two-stage coaxial multi-ribbed pulley

Embodiment Construction

[0013] As shown in Figure 1, the processing technology of the two-stage coaxial multi-ribbed pulley includes:

[0014] Blanking: Punch the thin-rolled steel plate into a circular plate on a punching machine;

[0015] Multi-step stretching: This embodiment includes three stretches on the hydraulic press. The first step is to stretch the blanked material on the hydraulic press to form a cylindrical workpiece for the first time. The second step is to stretch the blank for the first time. The finished cylindrical workpiece is turned upside down on the hydraulic press and stretched into a blank with two-stage pulley contours, and the third step is to stretch the blank drawn in the second stage through the hydraulic press to form a semi-finished product of two-stage coaxial multi-ribbed pulley;

[0016] Shaping: Shaping the semi-finished product of two-stage coaxial multi-ribbed pulley after multi-channel stretching on a hydraulic press;

[0017] Spinning processing: Spinning proce...

Abstract

The inventive belt pulley comprises bull and pony wheels integral formed by spinning of flat cold-rolled sheets. The process of manufacturing the belt pulley consists in: blanking; multistretching; shaping; spinning; punching and surfacing. The blanking is stretched into the semi-finished products for the two-stage coaxial multi-wedge pulley on the oil press by the multistretching and the times of multistretching can depend on the product conditions. The shaped and edged semi-finished pulley once-through complete the following process: spinning the big end and then spinning the small end by the spinning process.

Description

technical field [0001] The invention relates to a two-stage coaxial multi-ribbed belt pulley integrally formed by cold-rolled plates, a processing technique and equipment. The invention is suitable for all pulley transmission machines, especially for the automobile industry. Background technique [0002] Traditional belt pulley production is based on cast iron, cast copper, cast aluminum and alloys as blanks through mechanical processing. The product not only wastes resources, but also has a processing cost 30%-50% higher than that of extruded products, and more than 30% of material waste. At the same time, during the casting process The working environment is harsh, which is not conducive to environmental protection and wastes energy. In addition, due to the air holes in the casting main billet, the texture of the billet is uneven, and the balance performance of the pulley is poor. The pulley needs to be balanced after processing. Compared with the traditional pulleys that...
